| Abstract: | Many research works were completed to observe the critical applied temperature difference (ΔT)
c
in a small liquid bridge of floating zone. Different heating rates have been designed for detailed experiment, and relatively
high heating rate is especially demanded for space experiment due to the limited time of experiment. In the present paper,
the influence of heating rate on (ΔT)
c
was studied experimentally for cases of upper or lower rod heating for different geometry of liquid bridge. The results show
that there is large variation of (ΔT)
c
for different heating rate, changing from around 0.1°C/s to 1.6°C/s. This result is helpful for the design of Marangoni convection
experiment and the explanation of the dispersion of experimental results. |
